Document directory Monitored object Monitored object ø System (system) l % Total processor time Percentage of time when all processors in the system are busy. For a multi-processor system, this value can reflect the average busy status of all processors. The value is 100%, if half of the processors are busy, the value is 50% servers. Number of processors consumed by the server. If the server is dedicated

The previous article, "WMI for server Performance monitoring", describes how to get server performance through remote COM (which can also be used locally), so this article mainly says that the Windows system comes with performance monitoring----->performancecouonter. Open

performance counters to solve a database storage problem. During this process, I noticed some very strange phenomena: even though no operations are performed in the database, there are still write activities in the database files. This situation exists in both data and log files. This situation continues even when I make sure that I am not connected to SQL

memory. It can also be used as one of the reference indicators when making memory bottleneck decisions. 　　 Summarize The above mentioned several memory bottleneck pressure judgment indicators, but also only involves a part of memory-related counters, of course, including but not limited to the above values . If you do a memory bottleneck, you can have more reference values, The previous article also said, under memory pressure,

First, the basic information1. The Windows server performance counter data is passed. NET Diagnostics.performancecounter class to provide data;2. Diagnostics.performancecounter class can be CategoryName, CounterName, instancename and other parameters to determineThe performance counters that need to be obtained, these

Use WMI and performance counters to monitor remote server permission settingsZookeeper Application Scenario: on a web server, WMI is used in. NET encoding to query some hardware configuration information of the remote server, and perform
